Hybrid Tea rose plant named `Selbarium`

ABSTRACT

A new rose variety of the Hybrid Tea class, characterized by its continuous good production of large very soft pink with an orange blend flowers having a very good presentation, borne singly on upright stems on a bush of medium height (100-120 cm), and that is especially suitable for growing in Latin America considering the prevailing light intensity, day length and seasonal effects.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the Hybrid Tea class, which was originated by me by crossingthe unnamed seedling (Z37.116) with the unnamed seedling (SR 85.055).

The primary objective of this breeding was to obtain a new large typerose with a good presentation and bud shape in a trendy color having ahigh production. Among the novel characteristics possessed by the newvariety which distinguish it from its parents and all other varieties ofwhich I am aware are:

(1) A large flower and well shaped flower bud.

(2) The very soft pink color with an orange blend of the flower.

(3) Time of flowering is early to medium.

(4) Suitability for growing in Latin America.

(5) Rapid flowering cycles.

Asexual reproduction of the new rose variety by cutting and graftingusing R. canina `Inermis` as rootstock, as performed in a greenhouse inQuito, Ecuador, shows that the aforementioned characteristics anddistinctions come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The new variety of rose plant is illustrated by the accompanyingphotographic illustrations, of which:

Sheet 1 shows a full face view of the flower and

Sheet 2 shows typical specimens of the vegetative growth and flowers ofthe new variety in different stages of development and as depicted incolor as nearly true as it reasonably possible to make the same in colorillustrations of this character.

The following is a detailed description of this new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in the color description hereinrefers to plate numbers in the aforementioned color chart e.g. "55C" isplate "55C" of The Royal Horticultural Society Colour Chart.
